Number theory learning seminar 2014-2015
In the winter and spring the seminar will meet
Mondays 2:30--4:30pm in Room 384I on the first week of winter, and 384H in subsequent weeks.
This year's seminar will focus on the perfectoid spaces.
In the fall we will discuss adic spaces (and their relation with rigid-analytic geometry),
in the winter we will discuss the basics of perfectoid spaces (especially the tilting functor and
the almost purity theorem), and in the spring we will discuss some applications to
p-adic Hodge theory.
For more details on what each lecture will cover with references see here .
